Well, a new toy just appeared on my bench... this 37-640EZ (E for export, Z for New Zealand (I assume)). My understanding is that this cabinet was NZ made, but the chassis is a US-made export version and probably doesn't differ much to the standard US model other than the mains transformer.

Its in a bit of a state - the grille cloth is in good condition but I don't think its original to this cabinet, since I also have a 37-630EZ which has (I believe) factory cloth - which looks like the US cloth (but I'm open to opinions on that). Its also got a couple of capacitors screwed either side of the speaker and wired to a rats nest I have yet to decipher, but it also includes a switch that some thoughtful person has drilled a hole in the cabinet for reasons unknown - possibly an extension speaker arrangement of some sort - I'll know more when I can get myself off the couch (I'm currently suffering from the worst recorded case of man-flu ever )

The dial is cracked in several places and completely blank in one place where it looks like it has sat for years in the sun... and the glass is missing from the dial (although I have a spare NOS one I got for my 37-61 I can use)... And maybe the worst bit is the missing shadow-meter... I've had a quick look, but it doesn't appear to be there at all.
So I'm thinking I could possibly (and this is simply because I'm thinking bigger numbers are better, but I'm sure I can be educated on that fact ) make one really nice 37-640 from the two, and one not too bad 67-630 with the remains. I'll also put an advert up for a shadow-meter - how common are those to find (and with good coils?) ?
And is the main (only?) difference the push-pull output on the -640?
Here is the 37-630, which is in very nice original (I believe) condition:

Either way, I have a few other jobs to finish before I get into either of these... but its certainly tempting to get stuck into them... I love these radios. I've got a couple of sets of new rubbers sitting here for the tuning sub-chassis and to go under the main chassis and enough tube shields to do one, but I'll probably need to find a couple more of those too... I don't recall how many the -630 is supposed to have.
Anyway... more toys
